Pristimerin, a natural triterpenoid isolated form Celastrus and Maytenus spp, has been shown to possess a variety of biological and pharmacological effects. Recently, pristimerin has attracted more attention, especially for its potential anticancer activities. The anticancer activities of pristimerin have been illustrated in various cancer cell lines and animal models. It has been found to inhibit in vitro and in vivo proliferation, survival Read More

Urotensin II and Urotensin-II receptors are important molecular factors that regulate vasoconstriction and all the diseases that are linked to abnormalities in blood pressure regulation (i.e.: hypertension, kidney diseases, cirrhosis etc.). Recently, Urotensin II and its receptor have also been involved in metabolic syndrome, diabetes and schizophrenia. Recent strong findings suggest that Urotensin II and its receptor are involv Read More

Compared to normal cells, usually cancer cells are under higher oxidative stress. Elevating intracellular levels of reactive oxygen species (ROS) by introducing excessive ROS or inhibiting antioxidant system may enhance selectively of cancer cell killing by ROS-modulating agents through stress sensitization or stress overload. Meanwhile due to the adaptive response, normal cells may be capable of maintaining redox homeostasi Read More

With increases in our understanding of the human genome and immune system, the treatment armamentarium for melanoma has benefitted from the development and approval of BRAF inhibitors, MEK inhibitors, immune checkpoint modulators via cytotoxic T-lymphocyte antigen-4 blockade, and PD-1 and PD-L1 inhibitors. These advances, however, have raised questions about combination therapy, the optimal sequential use Read More

The evolution of genomic research enabled the genetic and molecular profiling of breast cancer and revealed the profound complexity and heterogeneity of this disease. Subtypes of breast cancer characterized by mutations and/or amplifications of some proto-oncogenes are associated with an increased rate of recurrence and poor prognosis. They represent a challenge in the clinic with limited arsenal to attack them. No Read More

Background: The epigenetic combinations of DNA demethylating agents and histone deacetylase (HDAC) inhibitors have demonstrated clinical benefits for non-small cell lung cancer (NSCLC) treatment, however, there are few studies uncovering the underlying molecular mechanism of the combinations. Our previous study showed that DNA demethylating agent Azacitidine (Aza) demethylated CpG sites in paired box gene 5 Read More

Background: ATP-binding cassette (ABC) transporters, P-glycoprotein (P-gp, ABCB1) and breast cancer resistance protein (BCRP/ABCG2) are major determinants of pharmacokinetic, safety and efficacy profiles of drugs thereby effluxing a broad range of endogenous substances across the plasma membrane. Overexpression of these transporters in various tumors is also implicated in the development of multidrug resistanc Read More

Background: Studies have demonstrated that cysteine-rich 61 (CYR61) may be involved in tumor proliferation and invasion. However, the role of CYR61 plays in endocrine therapy response is largely unknown. Patients and Methods: We tested the levels of CYR61 expression of 36 primary breast cancer patients who received neo-adjuvant endocrine therapy for at least 3 months by immunohistochemistry staining before an Read More
